Blade tensioning unit
The blade tensioning unit on these models is hydraulic. This means that the oil
level in the tensioning cylinder must be replenished whenever needed to ensure
correct operation of the unit. To replenish the blade tensioning cylinder, follow
the steps illustrated in the figures below.
When the piston protrudes from the blade tensioning cylinder by just 20 mm as
illustrated below, the cylinder must be topped up.
20 mm = 0.79 in.
Topping up sequence:
" Lower the head.
" Slacken the blade tensioning handwheel.
" Remove the filler cap using a hex wrench.
